Substitution reactions of halogermanes under nucleophilic assistance of tertiary amines or diazo derivatives leading readily to various functional derivatives of germanium have been carried out.Dehydrohalogenation of acidic halohydrogemanes under nucleophilic assistance is a useful way to divalent species, and the germylenes formed are stabilized by complexation with the nucleophilic agent.The reactions proceed via intermediate halogermylanions which lead to the formation of more stable germylenes.The transient halogemylanions have been characterized by means of their nuclophilic additions to carbonyl derivatives.Nucleophilic substitutions of halogermanes using these germylanions lead to the formation of polygermanes.
